Disk centrifuge with two axes can generate either constant or harmonic acceleration, and the parallelism of two axes has a great effect on the precision of the acceleration. In the assembling process of centrifuge the parallelism must be measured precisely, and corresponding adjustment or compensation measures must be taken. A series of coordinate systems is set up on the disk centrifuge,by way of the attitude relations among coordinate systems,the attitude matrix of workpiece plane coordinate system versus the geography coordinate system is deduced,on the basis of it,by mounting a two-dimension level on the workpiece plane,rotating the main axis and worktable axis respectively,sampling a series of data from the level,and carrying out harmonic analysis,then the parallelism of the worktable axis versus the main axis is gained.Finally,the effect of the parallelism on the measurement of static radius of the centrifuge is analyzed.
